Dissociatives 2-FDCK -- questions about ROA

Hello all, just wanted to ask some questions about 2-FDCK. I've read that it's better to take it orally, and I wanted to ask if people agree with that or have better luck using it in some other way, like nasally or sublingually.

If the bioavailability of oral dosing is actually greater than the other ROAs (except for anything with needles, I am not touching those) then that sounds great, but do people have any gastrointestinal side effects? Best to fast beforehand, eat lightly, or is it not important? Any nausea? My friends have all gotten pretty horrible nausea from DXM but not from K or FXE so I'm just a bit wary about eating a dissociative. Plus, if you were to mix it with, say, a pill of 4-HO-MET, would there be any concerns about nausea with that combination? I guess it doesn't matter too much as long as you aren't continually getting / feeling sick the entire experience. Still I am curious

Also, how is it plugged? Same as nasal?
 
Having both insufflated and eaten 2-fdck, I will say that the bioavailability is more or less equal via both ROAs. I personally did not have any gastrointestinal difficulties with oral administration, but I will say I am somewhat resistant to nausea or gastric distress so take that with a grain of salt. Fasting would probably be a good idea if you're trying to maximize potency by weight dosing orally, although definitely not necessary.

Try both ROAs and compare for yourself; I find the experience to be rather different via each route, and although having what is essentially orally active ketamine is great, I still prefer insufflated. There is something so magical about being relatively quickly blasted into the dissociative headspace. The slow comeup of oral dosing makes for an experience more similar to DXM in my experience. Anyways 2-fdck is fantastic, perhaps my favorite disso so enjoy.

How would you describe the difference in experience you're talking about between the two ROAs?

Your comment about it being more similar to DXM when taken orally sort of excites me, I like the layer of the DXM experience that is the headspace and dissociation quite a bit but could never love the substance because it gives me very harsh physical side effects compared to when I had first tried it. So if that's what you mean, that the oral dosing of 2-FDCK has more of a unique character compared to K, then I'm stoked.

Thank you for your reply!

The primary difference is the onset; ~5 minutes insufflated vs. ~45 minutes oral. I think this colors the experience greatly. With oral dosing, you are eased into the dissociation, producing a fundamentally different headspace/experience to the rapidity of insufflation. It also lasts like 3.5 hours orally so if you want your 2-fdck to last you as long as possible in terms of duration being intoxicated, go oral.

Yes, definitely a lot less physiologically taxing than DXM, no doubt about that. For me, 2-fdck (or any other dissociative for that matter) doesn't fully achieve the same 'wackiness' produced by DXM, but it's not too far off.

Definitely more unique than insufflating ketamine in my experience, although I feel this isn't too high of a bar since ketamine can be rather bland for me at lower-medium doses.
